"I have done a good deal in helping private collectors to buy art and I have been fortunate in that they have all bought because they love art. Once in a while someone has called me on the telephone to say, ‘‘I’d like to buy something that’s going to be eight times as valuable.” I say, “Well, I’m not interested. I only buy things myself because I’m crazy about them and I advise other people to do the same. If it becomes more valuable, that’s just good luck.” I don’t help anybody who says he wants to buy for investment purposes, I don’t like that as a reason for buying."
